Hello and hope you are doing well.
The itchiness could be due to contact dermatitis, that is exposure to an irritant like a chemical or metal or anything you are allergic to, it can cause itchiness and rash. It could also be due to dry skin, certain medications or sometimes due to systemic disorders like jaundice. But to exactly pinpoint the pathology you will need to consult your primary care physician who will examine you and may ask for blood tests. If the need arises he may refer you to a dermatologist.
Hope this helped and do keep us posted.
